Abstract

Divers aspects de la présente divulgation portent d'une manière générale sur la communication sans fil. Selon certains aspects, un équipement utilisateur (UE) peut recevoir une indication pour transmettre une communication associée à une autorisation configurée dans un réseau non terrestre (NTN), l'indication indiquant un identifiant de processus de demande de répétition automatique hybride (HARQ) et un indice d'autorisation configurée de la communication. L'UE peut effectuer une transmission de la communication sur la base, au moins en partie, de l'identifiant de processus HARQ et de l'indice d'autorisation configurée. De nombreux autres aspects sont décrits.
